Application April 14, 1939, Serial No. 267,856

3 Claims.

This invention relates to a portable double drive winding machine for articles like capicollo, Geneva salami, etc.

An object of this invention is the provision of 5 a machine for winding preserved meat articles quickly, uniformly and tightly.

Another object of this invention is to provide an automatically adjustable headstock for winding articles of different lengths.

Another object of this invention is to provide headstocks having a plurality of converging jaws with grooves of V-shaped cross-section in the engaging faces thereof, the said jaws being adapted to deeply engage the encased article being wound without penetrating the skin or casing thereof.

Another object of this invention is to provide a drive shaft having a thread substantially the entire effective length thereof, the said thread 20 being co-extensive with the distance between the headstock jaws in fully open position, so as to utilize substantially the entire area of the machine and make it compact.

With the above and other objects in view, the

25 invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawing and pointed out in the claims which form part of this specification.

Reference will now be had to the drawing, wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 1 is a plan view of the winding machine.

Figure 2 is a front elevation of the machine.

Figure 3 is a face View of one of the headstocks showing a plurality of spaced jaws of V-shaped cross-section.

Figure 4 is a side view of the cord carrier with the support for a ball of cord broken away.

In the illustrated embodiment of the invention, the numeral ll! indicates my portable double drive winding machine, comprising a base ll having handles i2 by means of which the entire machine may be carried to different parts of a provision manufacturing establishment and mounted on any suitable table or bench.

A frame l3 has been secured to the base H. The frame comprises upright supports M, which r are held in spaced relation by rods l5, l6 and Il and bolts 18, threaded therein from opposite ends of the supports M.

A headstock 20 has been rotatably mounted on a spindle 2i journalled in a bearing 22 in one of the upright supports M. The headstock 20 has a plurality of converging jaws 23, positioned diametrically of the headstock. Each of the jaws 23 has a groove of V-shaped cross-section, best shown in Figure 3, so as to form V-shaped engaging grooves adapted to grip an object placed between the headstocks at a plurality of linearly and diametrically disposed portions, especially that of an oval shaped end of an article being wound or bound.

A duplicate headstock 2!] has been rotatably mounted on a spindle Z4 journalled in a bearing 25 at the upper end of a bracket 26. The bracket 26 is slidably mounted on the rods I 5 and H6. The spindle 24 is also slidably mounted in a bearing 22 in one of the upright supports M. A co l spring 27 constantly forces the slidable headstock in direction of the non-slidable headstock. The V-shaped cross-sections of the grooves of the jaws 23 serve to substantially deeply engage the yielding exterior portionsof the article being wound without penetrating the skin or casing thereof.

The headstock spindles 2| and 24 have gears 30 secured thereto. A drive-shaft 3! has been rotatably mounted in bearings in the upright supports I4. Gears 32 have been secured thereto at opposite ends. An electric motor 33 has been fastened to the base H and through suitable pulleys 34, 35, imparts rotation to the driveshaft 3|. Gears 36 rotatably mounted in bearings in the upright supports M have been po itioned in meshed engagement with the gears 39 and 32 and when the motor is in operation cause both headstocks to be positively rotated in the same direction. 5

A handwheel 37 secured to the spindle 38 of one of the gears 36 serves for manually rotat ng the headstocks or for giving the headstocks a partial rotation at the finish of the winding operation when the motor is shut off and the winding cord has not reached the extreme end of the article being wound.

The winding of the article of provision is preferably accomplished with a cord. The cord feeder comprises a lead screw M] in the form of a square thread M cut on the drive-shaft 3!. The thread 4! extends substantially the entire effective length of the winding machine, that is, the length of the thread is co-extensive with the distance between the headstock jaws in fully extended or fully open position.

The cord carrier 42 comprises an elongated tubular portion A3 in slidable engagement with the rod I l. The cord carrier comprises an arcuate bar 44 having a semicircular and internally threaded body 45 adapted for engagement with the thread 4 I. A ball of cord 46 has been mounted on a support 4'! having an upper cord threading portion 48. The bar 44 has two spring-pressed threading members 49, 49, and an intermediate free threading eye-shaped guide member 50 and an aperture 5|. The cord 46 is threaded through guide member 50 and through the tensioning members 49, 49, as shown in Figure 4, for guiding and tensioning the cord. The member 50 serves to prevent knotting. The free delivery of an unknotted cord in position for winding is thereby assured.

As best shown in Figure l, the thread 4! terminates short of the hub of the pulley 35, leaving a reduced shaft portion 52 on which the internally threaded body 45 of the cord carrier 42 is brought to rest. This reduced or undercut shaft portion 52 is of a diameter corresponding to the bottom of the thread 4|. When the cord carrier 42 is fed by the thread in direction of the arrow, it assumes a stationary position when it reaches the shaft portion 52. This automatic arresting of the feed-motion of the cord carrier provides a safety feature in the operation of the machine. It is to be noted that an elongated keyway 53 has been cut in the spindle 24. The keyway in engagement with a key (not shown) in the gear 536. The key and keyway make the spindle 574i rotatable in all slidable positions.

It is to be noted that while I have shown a semi-circular and internally threaded body 65 for detachable engagement with the screw thread 4i, that I may employ a split threaded nut (not i T shown) in engagement with the screw thread and to detach both nut members from the thread, as is well known.

In accordance with the patent statutes I have described and illustrated the preferred embodiment of my invention, but it will be understood that various changes and modifications can be made therein without departing from the spirit of the invention as defined by the appended claims.

I claim:
